Toxic effect of venom of Australian snake, slf-hrm, sequela

This code signifies a long-term health problem or complication arising from a deliberate act of self-poisoning with venom from an Australian snake not otherwise specified. The patient intentionally exposed themselves to the venom, and the current encounter addresses a residual condition or late effect directly attributable to that past event.

Apply this code when documenting a sequela, such as chronic organ damage, neurological deficits, or persistent tissue necrosis, that resulted from a previous intentional self-harm attempt involving an unspecified Australian snake venom. This code is appropriate for follow-up visits or admissions where the primary focus is managing these lasting effects, rather than the acute poisoning itself.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past intentional self-harm event involving snake venom.
• Do not use for acute poisoning or if the intent was accidental or undetermined; refer to other T63.07x codes for those scenarios.
